Answer:
54
Step-by-step explanation:
the plot of land is an isosceles triangle, meaning two sides and angles are the same in value.
height (h)= 24
base (b)= 36
length (l)= 30
solution
find the area of triangle using area=half the product of the base and height.
A=1/2(36×24)
A= 216 square feet.
each tree needs 8 square feet
therefore using ratio and proportion,
1 tree= 8 square feet
x trees= 216 square feet
cross multiply and it'll be
216/8=x
therefore x= 54 trees

An equation for this would resemble this:
Now before we get into any equation solving let's get the <em>denominators </em>equal to each other. we can do this by <em>multiplying </em>the <em><u>numerator</u></em> and <u><em>denominator</em></u><em> </em>by 2.
Now we can solve the equation:
